Description

Technical Field

[0001] This application relates to the field of fluid tightness testing technology, specifically to a water flow verification tooling. Background Technology

[0002] In fields such as electronics and electrical engineering (e.g., microchannel cold plates), to ensure the structural integrity, functional reliability, and long-term stability of microcrystals under actual working conditions, water flow verification is required before shipment. This verification test necessitates the use of tooling to assist the tested microcrystal in meeting the test conditions. For microcrystals with non-integral structures (e.g., microcrystals composed of a cover plate and a main body bonded together), the test must consider not only the overall stability of the microcrystal and its internal airtightness, but also the strength of the connection (bonding) between different structures (the cover plate and the microcrystal body) and its resistance to water pressure. If the test fails (e.g., the cover plate is blown open by water pressure), the safety of the test personnel and the microcrystal must be ensured to prevent injury or damage.

[0003] The existing tooling cannot meet the above requirements. Therefore, it is necessary to design a new water flow verification tooling to assist the microcrystals under test in completing the test without affecting the test results, and to ensure the safety of the test personnel and the microcrystals under test.

If the test through hole is located on the sidewall of the target microcrystal, the support assembly includes: a pressure plate, which has a through hole adapted to the vent plug, and the pressure plate is fitted onto the vent plug. The surface of the pressure plate is perpendicular to the axial direction of the test through hole. A first L-shaped fixing plate includes a first horizontal plate and a first vertical plate that are perpendicularly connected to each other.

[0027] Example

[0028] This embodiment provides a water flow verification fixture, which assists a target microcrystal in completing a water flow verification test. The target microcrystal includes a cover plate 100 and a main body 200 bonded together. The target microcrystal has an internal flow channel, and its outer wall has multiple sets of through holes for connecting the internal flow channel to the outside. Each set of through holes includes at least one inlet hole and at least one outlet hole. Only one set of through holes is kept connected to the outside in a single test; the through hole connected to the outside is the test through hole, and the remaining through holes are reserved through holes. Specifically, this embodiment uses a cuboid-structured target microcrystal as an example. Figure 1As shown, the water flow verification fixture includes:

[0029] A sealing connector, one end of which is inserted into the test through hole and the other end is connected to a water inlet connector;

[0030] A water inlet connector, wherein the water inlet connector is sealed to the test through-hole via a sealing connector;

[0031] A sealing component, connected to the target microcrystalline material, is used to seal the reserved through hole;

[0032] Support components are connected to the target microcrystal, water inlet connector, or plug to fix the target microcrystal, water inlet connector, or plug.

[0033] A fixed base plate 8 is provided, on which a plurality of fixing holes for connecting support components are evenly provided.

[0034] Specifically, such as Figure 2 and Figure 5 As shown, the sealing connector includes:

[0035] A vent plug 1 is provided with a sealing ring on one end and a water inlet connector on the other end. The end of the vent plug 1 with the sealing ring is inserted into the test through hole, and the outer diameter of the sealing ring is larger than the inner diameter of the test through hole.

[0036] 1) If the test via is located on the sidewall of the target microcrystal, such as Figure 1 and Figure 5 As shown, the support component includes:

[0037] Pressure plate 2, the pressure plate 2 is provided with a through hole adapted to the vent plug 1, the pressure plate 2 is sleeved on the vent plug 1, and the plate surface of the pressure plate 2 is perpendicular to the axis of the test through hole;

[0038] The first L-shaped fixing plate 3 includes a first horizontal plate and a first vertical plate that are perpendicularly connected to each other. The first horizontal plate is fixedly connected to the fixing base plate 8. The first vertical plate is provided with a first screw hole for fixing the first lead screw 4. The surface of the first vertical plate is parallel to the surface of the pressure plate 2.

[0039] The first lead screw 4 has one end passing through the first screw hole and abutting against the pressure plate 2.

[0040] 2) If the test via is located on the bottom wall of the target microcrystal, such as Figure 4 As shown, the support component includes:

[0041] The bottom pressure plate 40 has a through hole that is adapted to the vent plug 1. The bottom pressure plate 40 is sleeved on the vent plug 1, and the plate surface of the bottom pressure plate 40 is perpendicular to the axis of the test through hole.

[0042] The bottom support 50 serves the same function as the first L-shaped fixing plate 3, which is used to fix the first lead screw 4, and the bottom support 50 is used to fix the third lead screw 60.

[0043] The third lead screw 60 has one end passing through the top plate of the bottom support 50 and abutting against the bottom pressure plate 40.

[0044] In this embodiment, the vent plug 1 is fixed by introducing a (bottom) pressure plate 2, and then the first lead screw 4 (third lead screw 60) passing through the first L-shaped fixing plate 3 (bottom support 50) abuts against and tightens the pressure plate 2. This not only ensures that the vent plug 1 is pressed tightly into the test through hole, but also ensures the stability of the water connector connection, realizing the sealed connection between the water connector and the test through hole, and providing the necessary conditions for the test.

[0045] Furthermore, such as Figure 1 and Figure 2 As shown, a connection window 31 is provided on the first vertical plate opposite the vent plug 1. The water connector can be connected to the end of the vent plug 1 exposed in the microcrystal through the connection window 31, which improves the convenience and stability of the connection.

[0046] Specifically, the sealing component includes:

[0047] A sealing plug 5 adapted to a pre-reserved through hole, one end of which is inserted into the test through hole and the other end is adapted to the end of the second lead screw 7;

[0048] If the test via is located on the sidewall of the target microcrystal, such as Figure 3 As shown, the support component includes:

[0049] The second L-shaped fixing plate 6 includes a second horizontal plate and a second vertical plate that are perpendicularly connected to each other. The second horizontal plate is fixedly connected to the fixing base plate 8, and the second vertical plate is provided with a second screw hole for fixing the second lead screw 7.

[0050] The second lead screw 7 has one end passing through the second screw hole and abutting against the end of the sealing plug 5.

[0051] Unlike the structure of the aforementioned fixed water inlet connector (sealing connection), this fixed sealing component lacks the pressure plate 2. This is because the sealing component here does not need to connect to other devices, and it does not even need to be exposed outside the test through-hole (e.g., Figure 3 As shown, its main function is to achieve a tight seal of the test through hole. The second L-shaped fixing plate 6 and the second lead screw 7 are mainly used to ensure the reliability of the sealing component. The end of the second lead screw 7 abuts against the end of the sealing plug 5 to prevent the sealing plug 5 from sliding out of the test through hole under the elastic action of the rubber ring, etc. For example, the sealing plug 5 and the vent plug 1 can adopt the same structure, but the end of the sealing plug 5 that contacts the second lead screw 7 needs to be perfectly matched with the second lead screw 7, or other caps can be used to seal the hollow channel of the sealing plug 5 to avoid air leakage. In addition, when the sealing component is not exposed in the test through hole, the second lead screw 7 can be threaded into the test through hole to tighten the sealing component inside the test through hole.

[0052] If the test through hole is located on the bottom wall of the target microcrystal, the support assembly for supporting the sealing component can refer to the structure of the fixed water connector (sealing connector) described above. Accordingly, the pressure plate 2 is removed, and the end of the screw directly abuts the sealing plug 5. This will not be elaborated here.

[0053] If the pre-drilled through-hole is located on the top wall of the target microcrystal (i.e., on the cover plate 100), it can be used as follows: Figure 1 The horizontal plate 20 shown serves as a support point for the lead screw used to tighten the sealing component. If the test through hole is located on the cover plate 100, the horizontal plate 20 can be used as a support point for the lead screw used to tighten the pressure plate 2. The remaining structure can be referred to the connection structure of the test through hole on the side wall, and will not be described in detail here.

[0054] Specifically, in this embodiment of the application, the supporting component includes:

[0055] Two support plates 9 are arranged in parallel. The top of the support plate 9 is provided with a groove that is adapted to the target microcrystal (to prevent horizontal displacement during the test). The two support plates 9 are respectively located on opposite sides of the target microcrystal and abut against the two side edges of the target microcrystal. The bottom of the support plate 9 is connected to the fixed base plate 8.

[0056] Multiple limiting blocks 10 are evenly distributed above the cover plate 100. Each limiting block 10 is connected to the top of the support plate 9 or to the horizontal plate 20. In this embodiment, there are five limiting blocks 10, located at the four corners and the center of the cover plate 100. The limiting blocks 10 at the four corners are connected to the top of the support plate 9, while the limiting blocks 10 in the center can be added... Figure 1 The horizontal plate 20 shown is connected to the cover plate 100. The horizontal plate 20 is located above the cover plate 100, and the surface of the horizontal plate 20 is parallel to the surface of the cover plate 100. The two ends of the horizontal plate 20 are respectively connected to the fixed base plate 8 through two brackets. Figure 1In this configuration, since the first L-shaped fixing plate 3 and the second L-shaped fixing plate 6 are respectively located on both sides of the target microcrystal, to save materials and improve the stability of the first L-shaped fixing plate 3 and the second L-shaped fixing plate 6, the first L-shaped fixing plate 3 and the second L-shaped fixing plate 6 are used as two supports for fixing the horizontal plate 20, with the two ends of the horizontal plate 20 connected to the top of the first L-shaped fixing plate 3 and the top of the second L-shaped fixing plate 6, respectively. The limiting block 10 here is mainly used to prevent the cover plate 100 from flying out under internal air pressure and injuring personnel. The limiting block 10 located in the middle of the middle cover plate 100 is mainly used to adhere the buffer pad 30, providing adhesion for the buffer pad 30 and preventing the cover plate 100 from breaking due to uneven force when it flies out.

[0057] Preferably, a buffer pad 30 is provided between the limiting block 10 and the cover plate 100, and the buffer pad 30 is bonded to the limiting block 10. Here, the buffer pad 30 is mainly used to provide cushioning when the cover plate 100 breaks open, so as to avoid damage to the cover plate 100. For example, the buffer pad 30 can be made of soft silicone.

[0058] In this embodiment of the application, the buffer pad 30 abuts against the cover plate 100, and the pressure of the buffer pad 30 on the cover plate 100 is less than the hydraulic pressure in the internal flow channel during the test.

[0059] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0060] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
